week 1 (quantifier)
all class material was reasonably easy to digest since it is the beginning of the course , however during the first tutorial we have huge argument with TA's solution on question 2 part D (false). Although TA's solution was correct , but some of the students questioning that there should be more than one solution (i'm one of them) , after long discussion we decided save the question and post on the PIAZZA.
Key notes of the week :
To prove universal claim , we have to check every single element pass the test and shows there is no counter-example.
To disapprove universal claim , we only need to find one counter-example.
To prove existential claim , find at least one example.
To disapprove existential claim , check every element , show there is no example

ReplyDeleteI hope you enjoy the course so far, and I think it is really good for you, keeping a summary of the week's material. I was really glad that you actually thought more on question 2(d) since that is the way of thinking needed in the course.
